Leviticus 18:10-12

The Voice

¹⁰ Do not have sexual relations with your son’s daughter or your daughter’s daughter; since they are your own flesh and blood, such an act would bring shame to you. ¹¹ You are not to have sexual relations with your stepsister, the daughter of your father and his wife;^[a] for she is still your sister. ¹² Do not have sexual relations with your father’s sister, your aunt; she is your father’s flesh and blood.
